I guess I should've included basic instructions... Arrow keys are normla, LEFT & RIGHT... UP or SPACE is jump. 1 (not keypad 1) is shoot basic ammo, and 2 is a super ammo (greater range and more damage)...

Experiment with it through several iterations and you start noticing the glitches in the zombie animations. Moving when he shouldn't, or the wrong animation, or not attacking when he should be, either skipping the Hit animation completely, or in a couple of instances, it just stopped on the hit animation and didn't do anything else. After trying it several times, it just doesn't feel right nor look right to me.
